Heavy-Duty 50kW Power – Built for 220V Applications

When the grid goes down and you need serious backup power, the EMEAN EM-W69 delivers a solid 50kW (62.5kVA) of prime power, backed by a 60kW WEICHAI WP4.1D66E200 turbocharged diesel engine. With voltage configurations available from 110V to 660V—including standard 220V options—this is a generator with 220 volt outlet capability that works seamlessly with North American and European electrical systems. Whether you are protecting a large home, a farm, or a small business, this generator keeps your 220V appliances, tools, and equipment running when you need them most.

The EM-W69 is more than just another generator with 220 volt outlet—it is a thoughtfully engineered power system that combines proven WEICHAI diesel technology with modern control features and a soundproof canopy for quiet operation. With a standby rating of 55kW (69kVA), this unit provides ample headroom for starting motors with high inrush currents and handling temporary load surges. The generator operates at 1500 RPM (50Hz) with a full-load fuel consumption of 16.59 L/h, making it a practical choice for standby and prime power applications alike.

Powered by WEICHAI – The 4.087L Workhorse

At the heart of this generator with 220 volt outlet lies the WEICHAI WP4.1D66E200, a 4-cylinder, 4.087-liter turbocharged diesel engine with an L-type cylinder arrangement【4†L4-L5】. With a bore and stroke of 105×118 mm and a compression ratio of 17.5, this larger-displacement platform delivers exceptional torque and thermal efficiency【4†L4-L5】. The engine achieves a mean effective pressure of 0.979 MPa and a mean piston speed of 5.9 m/s—a conservative figure that promotes long engine life by reducing wear on cylinder walls and piston rings【4†L8】.

What truly sets this engine apart is its remarkable oil consumption ratio of just 0.1% of fuel consumption, significantly lower than the industry average【4†L6】. With an oil capacity of 12L (low) to 14L (high), the EM-W69 is designed for extended service intervals that minimize downtime and maximize productivity【4†L6】. The engine maintains oil pressure between 300–500 kPa at rated speed, with a low-pressure alarm at 100 kPa to protect the engine from damage【4†L6】.

Built to Start in the Coldest Conditions

Cold weather reliability sets this generator apart from many competitors. The WP4.1D66E200 starts reliably down to -15°C without auxiliary starting devices, and with a preheater, it operates confidently down to -25°C【4†L4】. This exceptional cold-start capability makes the EM-W69 a practical choice for installations across North America and Europe, where winter temperatures can pose significant challenges for diesel equipment.

The 24V starting circuit is engineered with a maximum resistance of just 4 mΩ and uses 50 mm² wiring, ensuring ample current delivery to the starter even in the coldest conditions【4†L7】. A 4.5kW starter motor and 55A battery charging alternator provide robust starting power that you can count on every time【4†L6】.

Engineered for Quiet, Efficient Operation

The EM-W69 features a soundproof canopy lined with sound-reducing foam, making it a generator with 220 volt outlet that respects both residential and commercial environments. The industrial silencer and modular ventilation design further reduce noise levels, while the all-metal canopy parts are powder-coated for durability and corrosion resistance.

The engine’s thermal management is equally impressive. The closed-loop water cooling system is rated for operation up to 40°C ambient temperature, with a thermostat that begins opening at 76°C and reaches full opening at 89°C【4†L5】. Coolant flow is 6.1 m³/h, and the system holds 9.4L of coolant【4†L7】. At rated conditions, the cooling system removes 28.1 kJ/s of heat while the exhaust carries away 47.6 kJ/s, ensuring stable operating temperatures even during extended run times【4†L7】.

Clean, Efficient Combustion

The turbocharged WP4.1D66E200 draws 302 kg/h of air at rated conditions and 320 kg/h at standby, ensuring complete combustion and reduced emissions【4†L5】. The exhaust system is designed with a maximum back pressure limit of 10 kPa, allowing for flexible exhaust routing without compromising performance【4†L5】. Maximum exhaust temperature is capped at 560°C—significantly lower than many competitors—indicating robust thermal design that protects turbocharger components over the long term【4†L5】.

Complete Generator Set Features

The EM-W69 generator set is built around the WEICHAI engine and features a VG-224E brushless alternator with Class H insulation and IP23 protection. The alternator is available from leading brands including Stamford, Leroy-Somer, or Marathon, giving customers flexibility in their specification. The digital control panel (Smartgen or Deep Sea) includes auto-protection features such as overcurrent shutdown and low oil pressure alarm.
